JOHN E. WOOTTEN, OF PHILADELPHIA, PENNSYLVANIA.

GAGE-COCK.

Specication of Letters Patent. No. 23,136, dated March 1, 1859.

To all whom t may concern:

Be it known that I, JOHN E. VooTTEN, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in the Construction of Cocks for Gaging the Height of Water in Steam-Boilers; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a perspective view, Fig. 2 a front elevation, Fig. 3 a longitudinal verti cal section, and Fig. et a transverse section at cam C, showing the arrangement of means for actuating the valve E, similar letters referring to similar parts.

The nature of my invention consists in providing a tube A, a, the arm a., of which should be fixed as near to a right angle with tube A, as maybe desirable, and of such length as that when swung upward or downward, it may reach the highest or lowest level of water which should be contained within the boiler. At the upper end of arm a, is seated a valve E which is actuated by rod F, by means of cam C. Tube A passes through stufhng box B, and should be fre to revolve therein.

M, is a collar on tube A for the purpose of preventing any longitudinal play thereof.

C, is a cam, its purpose being to actuate the valve E, as will be hereinafter described.

On the outer end of tube A, is a conical faucet for the purpose of dischargingthe steam and water downward through the nozzle H.

I, is an index, which in connection with pointer P, indicates by means of figures upon its face, the height of water, in inches l above the lowest level which should be contained within the boiler. Y

K, is a spiral spring for the purpose of holding valve E upon its seat when the instrument is not in use.

Having thus described the construction of my improved gage cock, I will proceed to describe its application and mode of operation, which is as follows:` The stuffing box B, should be screwed into the boiler to a steam tight joint, and the tube A packed to a steam tight joint within the stuffing box B, by means of gland D. The valve E being closed, communication with the contents of the boiler is therefore cut o. When it is desired to ascertain the level of water in the boiler, the tube A, 0;, is moved around by means of lever R, the arm a, in its motion carries valve rod F over the projection of cam C, which causes valve E to be lifted from its seat, thus opening a passage through tube A, a. Vhen the level of the water in the boiler has been ascertained, by means of the end of arm a, having reached the surface set forth.
